There are approximately 40‚000 enzymes living in one human cell‚ each responsible for a chemical reaction. Enzymes are complex 3D protein molecules created by amino acids‚ forming a unique sequence that produces hydrogen bonds‚ eventually formulating an enzyme within plants and animals (Boyle & Senior‚ 2002). Working alongside other molecules‚ they uphold a stable reaction system. The function of an enzyme is to aid and increase chemical reactions and organise metabolism‚ while maintaining homeostasis

milk Introduction Enzymes are globular protein‚ responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon‚ hydrogen‚ oxygen and nitrogen (Gunsch‚ 2012). The role of enzyme is to act as catalysts‚ substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done by lowering the activation energy required to start a reaction. Enzymes are specific in

too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass of the solution. Methods and Materials: For part A of the experiment‚ the following items are needed: Dialysis tubing‚ IKI solution

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

Enzymes Enzymes are… * Biological catalysts Lower the energy level needed for a biochemical reaction to occur. This energy level is called activation energy. * Proteins Polypeptide chains made up of 100’s-1000’s of amino acids in a specific sequence. * Do not get “used up” in a reaction The number of “uses” of an enzyme depends on the enzyme. * Work more efficiently at certain optimum temperatures. * They are “reaction-specific”. Each enzyme is included in one reaction.

Liver and colon cleanse The colon and liver are very important organs in the body’s health with each having a specific task within the body when it comes to body detoxification. The colon is vital in eliminating wastes and water from the body‚ and the liver is responsible for filtering toxic substances and additives from the body. If both the two organs does not work correctly‚ waste full of dangerous substances and toxins can back up inside our body. This waste when left in our body can lead to

gallbladder according to Dorland ’s Medical Dictionary is the pear shaped reservoir for the bile on the posteroinferior surface of the liver‚ between the right and the left quadrate lobe‚ from its neck the cystic duct projects to join the common bile duct ’. The function of the gallbladder in the human body is to solve and concentrate bile‚ which is produced by the liver and is necessary for proper digestion of fats. What are Gallstones? Gallstones form when the liquid stored in
